Thumbnail Filmstrip of Grade 114 Qualitative Filter Paper Wet-Strengthened, 90mm Circle, 100/Pk Images
Whatman grade 114 quaitative filter papers are only half the thickness of Grade 113 and suitable for coarse or gelatinous precipitates. Smooth surface for easy recovery of precipitates.
These extremely strong filter papers have a high wet strength due to the addition of a small quantity of chemically stable resin. Normal qualitative applications will not introduce any significant impurities into the filtrate. The resins do, however, contain nitrogen so these grades should not be used in Kjeldahl estimations, etc.
